coffee
A place I used to work for, a rather large US telecom, at one time had nice break rooms with multiple Bunn coffee makers. You know the ones, been around since coffee was invented, fully plumbed, made coffee hot enough to make a McLawyer weep for joy. Folgers coffee, and it was pretty good for commercial coffee although I won't have the stuff in my house.
At some point it was decided that this was too expensive, so they switched out our fast, reliable coffee machines for those stupid pod people machines, and required that we bring in our own. The end result was, rather than people popping out for a quick cup before going back to their desks, maybe occasionally needing to wait the 3 minutes it took to brew a new pot, they had people lined up in the breakroom waiting to brew their personalized, individual cup of plastic coffee. Each cup took about 5 minutes while the machine trickled in the water, heated it up, then brewed the cup. For the first few hours, people who were on the clock would make their coffee, then go to the back of the line to wait their turn for another since the line was long enough that they'd be done with the first cup long before they got back to the machine for the second one. Some folks spent the first 3 hours of their workday in the coffee line. They went from paying about 100 bucks a month for coffee and supplies to losing the average hourly wage of 500 people x say 2 hours a day, and that company paid anywhere from 20 to 100 dollars an hour.
I just brought a small pot from home and made coffee at my desk which tasted tons better than the plastic stuff. If I'm going to have to buy my own anyway, I'm drinking the stuff I like.
